I must say it sounds like an odd use of the new Windows XP Home Media Center, but Toshiba is now offering a laptop featuring the OS.
I guess the part that doesn't make sense is that the home media center does stuff like record television and manage a library of music, movies, and photos, but this laptop is portable. Doesn't that defeat the time-shifting if you have to come home to plug your machine so you can tape your favorite show?
